Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gravity is used to press hydrogel on the perforated plate, then the chopping operation can be performed, but the pressure is not uniform and chopping is unstable
Solution Approach 1:
The patent introduces a rotating screw that dynamically presses the hydrogel against the perforated plate during rotation. This dynamic pressing mechanism replaces static gravity-based pressing, ensuring uniform contact pressure throughout the chopping process and achieving consistent particle size distribution.
Solution Approach 2:
The screw acts as an intermediary mechanism between the hydrogel and the perforated plate. Instead of relying directly on gravity to press the hydrogel, the screw mediates the pressing action, distributing force uniformly across the hydrogel surface and enabling stable chopping operation.
2Productivity
If the hydrogel is simply pulverized to increase surface area, then the drying efficiency can be improved, but the chopping operation becomes unstable
Solution Approach 1:
The rotating screw provides continuous dynamic pressing and chopping action, maintaining stable operation while effectively increasing the surface area of hydrogel particles. This dynamic mechanism ensures both high productivity for drying and reliable chopping stability.
Solution Approach 2:
The screw performs preliminary chopping and size reduction of the hydrogel before it reaches the perforated plate for final particle discharge. This preliminary action prepares the hydrogel for efficient drying while maintaining operational stability throughout the process.
